.DISCUSSION...
Today and Tonight...Isolated storms will remain possible as day 
breaks across the ArkLaMiss this morning as a couple of outflow 
boundaries, one over East Central Mississippi and the other moving 
into Southeast Mississippi, slow their southeast progression.  With 
high pressure aloft building deeper into the region today from the 
west and the aforementioned slowing boundaries, it'll be primarily 
over East and Southeast Mississippi where the better rain chances 
will reside this afternoon.

Although high-res models agree with this scenario today, they 
haven't exactly performed stellar over the past 48 hours.  So, 
attention to radar and satellite will need to be paid upstream under 
this continued northwest flow for any MCS or outflow activity that 
could propagate southeast into the region, potentially initiating a 
better coverage of convection during the today period.

Speaking of northwest flow and MCSs, global and high-res models are 
in good agreement with a potentially stout affecting mainly the 
eastern half of the CWA during the overnight hours.  With plenty of 
instability hanging on overnight in this warm and moist airmass, 
steep mid-level lapse rates, and adequate deep-layer wind shear, 
some severe storms will be possible with this complex as it affects 
the area later tonight.  Currently, the better potential for severe 
storms will reside along and northeast of a Greenville to Meridian 
line, where a "Slight Risk" for severe storms exists.  A narrow 
"Marginal Risk" area reside outside the "Slight Risk" are from 
Hamburg, AR, to Jackson, to Laurel.  Isolated severe storms are 
possible within this "Marginal Risk" area.  Severe storms will be 
capable of producing damaging wind gusts and large hail.  In 
addition, nearly continuous lightning and torrential rainfall can be 
expected as will with this complex as well.

Before we get to the severe weather threat for tonight, dangerously 
high levels of heat stress will continue today.  Afternoon highs 
ranging from the mid 90s to around 100, coupled with dew points in 
the 70s, will again promote afternoon heat index values between 105-
110, especially across the Delta region.  As a result, another "Heat 
Advisory" has been hoisted for today from 11 AM until 8 PM.  If 
either temperatures or dew points run higher than what's currently 
being forecast this afternoon, portions of this "Heat Advisory" may 
need to be escalated to an "Excessive Heat Warning".  Lows 
tonight will again remain mild, and fall into the 70s. /19/

Saturday through Thursday: The primary concerns will be heat stress 
and rain chances through the period. 

The period will be characterized by anomalous mid to upper ridging 
west to mid to upper troughing over eastern conus. This will bring 
northwest flow to the region during the period. The ridging will 
contract some toward the west on Saturday as upper troughing becomes 
dominate from the north. Meanwhile anomalous low to midlevel temps 
will continue on Saturday but will decrease on Sunday. This will 
result in highs in the middle to upper 90s with some triple digit 
numbers west of the MS River on Saturday. This will bring heat 
indices from the around 105 to 113. The warmest indices will be over 
the western areas mainly Saturday,which will decrease in coverage on 
Sunday. So will maintain the heat risk in the HWO for Friday through 
Sunday. Models indicate that some strong storms will be possible on 
Saturday into Saturday night with northwest flow aloft. We will have 
0-3km winds of around 35 knots, Vertical totals in the lower 30s in 
the north,a frontal passage for lift, and good lapse rates. CAM 
guidance shows a good line passing in the TN valley to the north and 
east , along with isolated activity across our area. SPC has a 
marginal risk for our eastern areas, since we have a severe risk for 
today will hold off on that for the graphics for now. As we push 
through the weekend the axis of the upper trough will spread over 
the remainder of the region by Sunday. An associated upper low will 
with another frontal boundary will push south across the Lower 
Mississippi Valley On Wednesday. The weak closed low will wash out 
over the SE Conus as upper flat ridging takes over. This will keep 
rain chances across the region for the upcoming workweek with our 
soupy airmass.

As far as temperatures are concern beyond this weekend with the 
frontal passage readings will tone back to mainly from the upper 80s 
to the lower 90s. Lows will be in the lower to middle 70s./17/

JULY 20TH...HISTORIC WEATHER EVENTS
...1930...
The temperature at Washington D.C. soared to an all-time record of 106
degrees. The next day Millsboro reached 110 degrees to set a record for the
state of Delaware. July 1930 was one of the hottest and driest summers in
the U.S., particularly in the Missouri Valley where severe drought
conditions developed. Toward the end of the month state records were set
for Kentucky with 114 degrees, and Mississippi with 115 degrees. (David
Ludlum)
...1934...
The temperature at Keokuk IA soared to 118 degrees to establish a state
record. (The Weather Channel)
...1953...
Twenty-two inches of hail reportedly fell northeast of Dickinson ND. (The
Weather Channel)
...1986...
The temperature at Charleston SC hit 104 degrees for the second day in a
row to tie their all-time record high. (The Weather Channel)
...1987...
Thunderstorms produced severe weather across Minnesota, Wisconsin and
Michigan. Thunderstorms produced wind gusts to 87 mph at Mosinee WI, and
strong thunderstorm winds capsized twenty-six boats on Grand Traverse Bay
drowning two women. Thunderstorms produced nine inches of rain at Shakopee
MN, with 7.83 inches reported in six hours at Chaska MN. Thunderstorms in
north central Nebraska produced hail as large as golf balls in southwestern
Cherry County, which accumulated to a depth of 12 inches. (The National
Weather Summary) (Storm Data)
...1988...
The temperature at Redding CA soared to an all-time record high of 118
degrees. Showers and thunderstorms produced much needed rains from New
England to southern Texas. Salem IN was deluged with 7.2 inches of rain
resulting in flash flooding. (The National Weather Summary)
...1989...
Showers and thunderstorms in the Middle Atlantic Coast Region soaked
Wilmington DE with 2.28 inches of rain, pushing their total for the period
May through July past the previous record of 22.43 inches. Heavy rain over
that three month period virtually wiped out a 16.82 inch deficit which had
been building since drought conditions began in 1985. Thunderstorms in
central Indiana deluged Lebanon with 6.50 inches of rain in twelve hours,
and thunderstorms over Florida produced wind gusts to 84 mph at Flagler
Beach. (The National Weather Summary) (Storm Data)
